What  else might people do when they miss some procedural requirements for 
manufacturers exchange scheme? 
They throw it on the second hand market and sell it via ebay to people like 
me....

The type of the NIC matches.
but at least, this one test misses out

:~/tmp/hp> ./ifcheck 00:1f:29:61:0b:25 00:1f:29:61:0b:26 00:1f:29:61:0b:24 
00:1f:29:61:0b:27
OK
OK
OK
OK

well, but how reliable is this tool??? .... 

:~/tmp/hp> ./ifcheck th:is:is:bu:ll:sh
OK

Hm... so you agree that a firmare issue _might_ be a plausible cause?

So I'll google for either a fw upgrade,
 or ebay for a Intel branded card, like the first one I have.

http://h30499.www3.hp.com/t5/Networking/firmware-for-HP-NC364T-NIC/td-p/4750799#.VQb_mmznHRY

The HP card with quirks:
root@cruncher:~/hp# ethtool -i eth8
driver: e1000e
version: 2.3.2-k
firmware-version: 5.12-2
bus-info: 0000:08:00.1
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: no

The Intel card which works: 
root@cruncher:~/hp# ethtool -i eth4
driver: e1000e
version: 2.3.2-k
firmware-version: 5.10-2
bus-info: 0000:0d:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: no


So the card that works fine has the older firmware.
Should I downgrade ???
Can I??

Where to find?
HP ? I can confirm this finding:

http://h30499.www3.hp.com/t5/ProLiant-Servers-ML-DL-SL/Firmware-Update-for-nc364t/td-p/4744564#.VQb_nmznHRY
	I have checked, NC364T does not have firmware available for download 
	on HP site. That probably means, 
	there is not firmware update available for this NIC.

Same holds true for Intel & 82571EB firmware

next match is - well, that's why I am on this list...

> I don't know if those are very helpful, sorry!
No reason to sorrow.
Any input from professionals is of value for the lonely fighter :-)
Thank you !

I think if it were a common / simple / known issue, this list were the place 
where people knew about it. 
If it rings no bell with nobody, I'II have to change the board.
